Terry Gilliam directs this comedy adventure starring Adam Driver and Jonathan Pryce. While shooting a commercial in Spain, advertisement director Toby Grisoni (Driver) revisits the student film he made nine years earlier and goes in search of its star, cobbler Javier (Pryce), who is now convinced that he is Don Quixote and Toby is his squire, Sancho Panza. Together, they set off on an adventure, with Toby increasingly unable to distinguish his dreams from reality.
